, guppies do not need oxygen pumps, because the oxygen content in their wild environment is not very high. And the guppy is a small fish, the ability to consume oxygen is not strong, so the normal breeding is the need to install oxygen pumps. However, if the breeding density is high, such as a 40 cm fish tank, up to 30 guppies, if the number is more, it is recommended to install oxygen pumps. It is also recommended to install oxygen pumps for small guppies, because they are fragile and do not recommend changing water when they are born, so three hours of oxygen a day is conducive to their growth and development.
Whether guppies need to install heating rods depends on the water temperature. The most suitable water temperature for them is 22-24 ℃. If the water temperature can reach more than 22 ℃ in the usual feeding process, there is no need to install heating rods. If the water temperature can not reach 22 C, it is necessary to install a heating rod. Guppy is a tropical fish, and the temperature in most parts of our country in winter is relatively low, even if there is indoor heating, it can not reach more than 22 degrees Celsius, so it is recommended to install heating rods in winter to maintain the temperature.
